Application led March 2,

To all w 710m t may concern Be it known that I, WILLIAM F. H. BRAUN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Slicing-Machines, of which the following is a specification.

The principal object of the present invention is to provide simple, efficient and reliable mechanism for feeding the meat table only at times when the carriage which carries the meat table is at a part of its stroke remote from the knife, so that the meat will be fed into cutting position only when it is clear of the knife and between the slicing operations.

To this and other ends hereinafter set forth the invention comprises the improvements to be presently described and finally claimed.

In the accompanying drawings, forming part hereof, there is illustrated an embodiment of the invention selected from other embodiments for the sake of description, and

Figure 1 is an inverted plan of so much of a meat slicer as is necessary for an understanding of the invention, and

Fig. 2 is a sectional elevation of the same.

In the drawings 1 is a carriage and 2 is an oscillating pin by which it is moved back and forth endwise of the machine and on the xed bed 3, for example, by means of the rotary arm 4 and link 5 pinned to the pin 2. 6 is a meat table movable crosswise of the carriage, for example, by means of the screw feed 7, actuated by a pawl 8 and toothed wheel 9. These are usual parts of known slicing machines and need no detail description. 1() is an oscillating shaft provided with a radially arranged follower or nutpin 11, and it is mounted for rotary oscillation in the carriage 1, and by means of a sector-gear 12, this oscillating shaft is geared to the toothed wheel 13, that reciprocates the pawl arm and actuates the screw feed 7 in order to feed the meat table 6. 14 is a traveling nut having a groove or slot 11a and mounted for endwise reciprocation, but not turning movement on the oscillating shaft 10, and it is reciprocated by a crank arm 15 fast on the pin 2 and having slot-and-pin connection 16 with a bracket 17 provided on it.

In the operation of the machine, the pin 2 g Specification of Letters Patent.

is oscillated through a portion of a turn by the action of the operating mechanism 4 and 5 1n reciprocating the carriage 1 back and forth on the bed 3, toward and away from the knife which is not shown and well understood, and arranged at the top of the sheet although not shown for lack of space and because too well understood to require illustration. rlhe oscillation of the pin 2 the groove 11a are such that the pawl and feed mechanism 8 and 7 are properly operated to feed the meat table 6 whenthe carriage 1 is traveling the portion of its stroke remote from the knife (upper in Fig. 1) end of the machine.

I claim:

1. Feed mechanism for slicing machine meat tables comprising the combination of a traveling carriage, a reciprocatable nut, an oscillatory shaft mounted on the carriage and provided with a nut pin cooperating with the nut, a pawl arm carried by the carriage, and tooth gearing interposed between the pawl arm and shaft, substantially as described.

2. 1n feed mechanism for slicing machine meat tables the combination of a traveling carriage, a reciprocatable nut and an oscillatory shaft cooperating with the nut and mounted on the carriage, the combination and construction being such that movement of the carriage reciprocates the nut and the reciprocation of the nut oscillates the shaft, substantially as described.

3. Feed mechanism for slicing machine meat tables comprising the combination of a carriage, an oscillatory pin by which the carriage is reciprocated, an oscillatory shaft mounted for turning movement in the carriage and provided with a radially arranged nut-pin, a meat table slidable on the carriage and having a feed screw, pawl actuated feed mechanism between the shaft and screw, and a non-rotatable nut slidable on the oscillatory shaft and actuated by the pin and engaging the nut-pin, substantially as described.

4. Feed mechanism for slicing machine meat tables comprising the combination of a carriage and a. meat table, an oscillatinfcg` pin by which `the carriage and meat table are reciprocated, mechanism for feeding the table in respect to the carriage, and a travcling nut and oscillatory shaft carried by the carriage and interposed between the pin and-feeding mechanism and of which one is reciprocated rectilinearly and the other is oscillated revolubly, substantially as described.

5, Feed mechanism for slicing` machine meat tables comprisingl the combination of a carriage,` an oscillating pin by Which the carriage is reciprocated and which is provided with a crank arm, an oscillatory shaft mounted vfor rotary oscillation in the carriage and provided with a radially arranged nut-pin, a nut engaging` the nut-pin and mounted on the oscillatory shaft for end- Wise reciprocation by said arma meat table slidable on the carriage, andfpaivl driven mechanism carried by the table and operated by the oscillatory shaft for feeding the meat table in respect to the carriage, substantially as described.

6. Feed mechanism for slicing machines comprising the combination of a carriage, means for reciprocating the carriage, a meat table and its feed mechanism mounted on the carriage, Va nut and oscillatory shaft mounted on the carriage', provisions interposed betiveen the nut and carriage reciprocating means to cause the nut to -travel andV oscillate the oscillatory shaft, 'and con nections between the oscillatory shaft and feed mechanism to operate the latter from the former, substantially as described.
